Patrick Mahomes did not hide his frustration after the Kansas City Chiefs suffered a crushing 20-3 defeat to the Seattle Seahawks on Sunday night, delivering a blunt assessment of a performance that exposed serious problems on both sides of the offense.
The loss ended Kansas City's unbeaten start to the 2026 NFL season and left Mahomes searching for answers after one of the most difficult outings of his career.

The three-time Super Bowl MVP completed 19 of 33 passes for 165 yards, threw an interception and failed to record a touchdown as Seattle's defense controlled the contest.
Speaking after the game, Mahomes was particularly disappointed with the team's lack of preparation and execution.
The quarterback acknowledged that the Chiefs had been outplayed and challenged his teammates to show a different response when they return to the field.
"This sucks. You don't want to perform like this in primetime. You've got to feel it on the plane ride home... You've got to see your mistakes... and try to play better... and find a way to win next week," he said.
His words reflected the scale of the disappointment in Kansas City. The Chiefs entered the matchup with a 5-0 record, but they were unable to find an answer to Seattle's defensive pressure or generate the explosive offensive plays that have frequently defined Mahomes' career.
The quarterback also accepted that the team had not done enough to meet the challenge presented by the Seahawks.
"If you don't come ready to play, you can get your tail kicked in this league, we have a young team, it'll be how we respond from this," Mahomes said.
Kansas City now has to demonstrate that the setback was an isolated failure rather than the beginning of a wider problem.

The statistics highlighted just how unusual the performance was for a team led by Mahomes. Kansas City managed only three points and 213 total yards, while the offense failed to reach the red zone even once.
According to ESPN Insights, the three-point total matched the fewest the Chiefs have scored in any of the 153 games Mahomes has started, including the playoffs. The team's yardage total was also its second-lowest across those appearances.
Seattle's defensive pressure played a major role. Mahomes was under pressure on 19 of 36 dropbacks, making it difficult for him to establish a rhythm or give his receivers enough time to get open.
His interception added to Kansas City's difficulties, and the team never found the end zone.
The absence of key wide receivers Rashee Rice and Tyquan Thornton also complicated the quarterback's task, limiting the available options in the passing game.
However, the Chiefs struggled to establish consistency across the offense, with the running game offering little relief.
Kenneth Walker III, who arrived in Kansas City after winning Super Bowl MVP honors with Seattle last season, was restricted to 36 rushing yards on 14 carries.
Mahomes acknowledged that the team needed to create more opportunities for the running back, explaining that Kansas City had to become more effective through play-action and movement when opponents concentrated on stopping the run.
Head coach Andy Reid also accepted responsibility for the defeat rather than placing the blame entirely on his players.
"Listen, all three phases we struggled, so we've got to do better, and that's my responsibility," Andy Reid said after the game. "So I take full responsibility for this. We've got to play better as a team."
The Chiefs will need to turn those words into action quickly. Their next game is a divisional showdown against the Denver Broncos, with the result potentially having significant consequences for the AFC West standings.
Kansas City fell to 5-1 after the Seattle defeat, while Denver improved to 5-2, leaving the teams separated by half a game.
For Mahomes, the immediate priority is correcting the mistakes that allowed Seattle to dominate.
The quarterback has built his reputation on delivering under pressure, but Sunday's performance showed how vulnerable Kansas City can become when its offense cannot sustain drives or generate points.
His message was clear: the defeat cannot be ignored, and the Chiefs must respond with a much-improved performance against Denver.
After a night in which almost nothing worked, Mahomes and his teammates have little time to dwell on the disappointment before facing another crucial test.
